TECHNICAL FIELD

The subject matter described herein relates to the authentication of users to software systems using password-less techniques including biometric-based authentication.

BACKGROUND

In order to access an information technology (IT) resource (e.g., software application(s), data, and/or the like), users are often required to authenticate themselves to the system providing the IT resource. For example, if a user wishes to access their personal checking account through an online banking application, the user may be required to enter a username, a password, etc. and/or to provide an additional authentication code (e.g., a temporary code which the bank provides to a known device associated with the user). Although these authentication measures generally increase security and reduce the potential that a user's personal information may be compromised, work-a-rounds to these measures are often discovered and exploited.

SUMMARY

Data is received as part of an authentication procedure to identify a user. Such data characterizes a user-generated biometric sequence that is generated by the user interacting with at least one input device according to a desired biometric sequence. Thereafter, using the received data and at least one machine learning model trained using empirically derived historical data generated by a plurality of user-generated biometric sequences (e.g., historical user-generated biometric sequences according to the desired biometric sequence, etc.), the user is authenticated if an output of the at least one machine learning model is above a threshold. Data can be provided that characterizes the authenticating.

The desired biometric sequence can be pre-defined, or alternatively, it can be dynamically selected or generated. For example, the desired biometric sequence can be dynamically generated using at least one biometric sequence generation machine learning model.

Training data can be used as part of a training process prior to the authentication procedure. Such training data can form at least a part of the empirically derived historical data. The training of the at least one machine learning model can be static or it can be ongoing (i.e., the at least one machine learning model can be adaptive and continually refining itself, etc.).

The authenticating can include initially determining whether the user correctly completed the biometric sequence.

The at least one machine learning model can include a model utilizing at least one of: supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning. For example, the at least one machine learning model can utilize one or more of: random forests, nearest neighbor models, naive Bayes, decision trees, linear regression models, support vector machines (SVM), neural networks, k-means clustering, Bayesian methods, statistical methods, bootstrap models, Q-learning models, temporal difference (TD) models, or deep adversarial networks.

The provision of data can include providing access to a biometric cryptographic key if the received data is successfully authenticated. In some variations, a prompt can be provided, in a graphical user interface presented to the user, soliciting the user to provide an alphanumeric password. Thereafter, via the graphical user interface, user-generated input can be received that includes an inputted password. The password can then be locally encrypted using the biometric cryptographic key. Further, the biometric cryptographic key can be used to decrypt a locally stored domain password.

The biometric cryptographic key can be programmatically generated based on one or more attributes of a computing device used to execute the desired biometric sequence.

The received data can include a vectorization of various action values forming part of the user-generated biometric sequence in a vector. The authenticating, in this case, includes individually determining, using that each part of the at least one machine learning model, that each action value forming part of the vector indicates that the user-generated biometric sequence was performed by a desired user. Further, for each successfully authenticated action value, a corresponding portion of the biometric cryptographic key can be provided, and the portions of the biometric cryptographic key can be concatenated to result in a final biometric cryptographic key.

The threshold, in some variations, can be static and pre-defined. Further, the threshold corresponds to a confidence level. Such confidence level can dynamically change.

The providing data characterizing the authenticating can include one or more of: causing such data to be displayed in an electronic visual display, loading such data into memory, storing such data in physical persistence, transmitting such data to a remote computing device.

Non-transitory computer program products (i.e., physically embodied computer program products) are also described that store instructions, which when executed by one or more data processors of one or more computing systems, cause at least one data processor to perform operations herein. Similarly, computer systems are also described that may include one or more data processors and memory coupled to the one or more data processors. The memory may temporarily or permanently store instructions that cause at least one processor to perform one or more of the operations described herein. In addition, methods can be implemented by one or more data processors either within a single computing system or distributed among two or more computing systems. Such computing systems can be connected and can exchange data and/or commands or other instructions or the like via one or more connections, including but not limited to a connection over a network (e.g., the Internet, a wireless wide area network, a local area network, a wide area network, a wired network, or the like), via a direct connection between one or more of the multiple computing systems, etc.

The subject matter described herein provides many technical advantages. For example, the current subject matter provides enhanced techniques for biometrically authenticating users which, in turn, reduces the likelihood of unauthorized users accessing software systems. Moreover, the current subject matter is advantageous in that it provides higher levels of security while, in some implementations, avoiding the need for using alphanumeric passwords which are often simplistic in nature and easier to defeat.

The details of one or more variations of the subject matter described herein are set forth in the accompanying drawings and the description below. Other features and advantages of the subject matter described herein will be apparent from the description and drawings, and from the claims.

DETAILED DESCRIPTION

The current subject matter is directed to systems, apparatus, methods, and computer-program products for password-less authentication techniques for access to software systems/computing resources. These techniques can be standalone or used in connection with other techniques such as conventional user name/password login prompts and the like. Further, these techniques utilize machine learning to more precisely characterize the actions of user as being genuine as opposed to a malicious actor trying to mimic the user's actions.

The authentication techniques herein can utilize a biometric sequence that involves a user taking a sequence of movements/actions using one or more input devices of a computing device (e.g., tablet, mobile phone, laptop, desktop, IoT device, etc.).

In particular, machine learning models are used to characterize and differentiate how a particular user handles input devices such as a touchscreen, a keyboard, a track pad, and/or a mouse during an authentication process. An authentication sequence as used herein can comprise a biometric sequence in which the input device is used to execute a sequence of actions. These actions can be movements (for example according to a grid or other pattern which requires numerous individual movements), an activation of a graphical user interface (GUI) element, activation of an input device element (e.g., clicking a button, moving a track pad or roller, etc.).

In some variations, in order for the machine learning models to be tailored to a particular user, these machine learning models must first be trained. The training period requires that the user repeat the biometric sequence numerous times. An authentication application can, for example, prompt the user to perform the sequence multiple times, perhaps throughout multiple days (deemed as the “training period”) so the machine learning model(s) may continuously fine-tune itself. In some other variations, the training is continual (i.e., the models are adaptive, etc.) in that the models can be “fine-tuned” based on user actions for each subsequent execution of the biometric sequence.

In some variations, the biometric sequence can be analyzed using two factors. First, a determination can be made as to whether the user completed the biometric sequence. This determination does not necessarily require the use of a machine learning model. Second, a determination can be made as to whether the user behavior when completing the biometric sequence is likely to have been performed by the corresponding user. This second determination can use at least one machine learning model which is trained during the training period.

In some case, the biometric sequence is pre-defined so that the user repeats a known sequence numerous times and each of the actions forming part of the sequence are characterized. For example, with reference to diagram 100 of FIG. 1 , a GUI of the computing device (e.g., mobile phone, etc.) may include a grid of points and the pre-defined biometric sequence requires the user to input a backwards “Z” across the points of the grid with the user activating an input device at each point of the “Z”. In other cases, with reference to diagram 200 of FIG. 2 , the biometric sequence is generated by the user during the training period. For example, the user may opt to create a spiral shape via an input device of the computing device and repeat such shape numerous times during the training period. Optionally, the user may also activate an input device at various points along the spiral (e.g., depress touch screen at beginning and end of spiral, etc.).

In another variation, the biometric sequence is not pre-defined but rather, is either generated on the fly or is randomly selected from a large number of available biometric sequences. In either event, a machine learning can be used to generate/modify the “rules” or the “types of sequences” that a user inputs, in order to maximize the ability of the models to recognize the particular user. The biometric sequence can be dynamically modifiable according to the machine learning algorithms to decrease the likelihood of third parties from successfully executing the biometric sequence (as determined by the machine learning models). Described differently, the machine learning models (with regard to biometric sequence generation) can constantly experiment with what actions/sequences comprise the biometric sequence.

Various attributes that characterize the biometric sequences are recorded during each execution of the biometric sequence during the training period. For example, with the example of FIG. 1 , the speed at which each line forming part of the backwards “Z” is drawn, the amount of rest time at each end point of the backwards “Z”, the X-Y coordinate deviations of each line, the pressure applied for each line and/or at each end point, and the like.

In one example, values for the attributes can populate a 20-dimensional vector that characterizes:

Time for left-click or drag-n-drop

Time for right-click

Time 1 for double-click

Time 2 for double-click

Time 3 for double-click

Direction of mouse movement or drag-n-drop

Line binned of mouse movement or drag-n-drop

Line velocity of mouse movement or drag-n-drop

Curve binned of mouse movement or drag-n-drop

Curve velocity of mouse movement or drag-n-drop

Curve acceleration of mouse movement or drag-n-drop

Ratio of curve to line of mouse movement or drag-n-drop

Offset of mouse movement or drag-n-drop

Error of mouse movement or drag-n-drop

Variability of mouse movement or drag-n-drop

Curvature of mouse movement or drag-n-drop

Curvature rate of mouse movement or drag-n-drop

Curvature velocity of mouse movement or drag-n-drop

Curvature acceleration of mouse movement or drag-n-drop

Angular velocity of mouse movement or drag-n-drop

The various attributes in the vector can be used to generate a biometric cryptographic key that is unique to the user. This biometric cryptographic key can be generated by encrypting the vector using, for example, AES 256 algorithm or the like. In other variations, the biometric cryptographic key can be programmatically generated by the product based one or more computing device specific attributes, and the key then be associated to the vector.

In some variations, the biometric cryptographic key can be a concatenation of key portions that each correspond to one of the attributes in the vector. For example, the biometric cryptographic key can be stored as a portion of different key portions and each key portion is returned only if the conditions (as determined by the machine learning model) deem that the attribute values indicate that the correct user performed that portion of the biometric sequence.

During run-time (i.e., after the training period, etc.), the user is prompted or otherwise causes a biometric sequence to be entered via the interface of the computing device (either directly through a touch screen and attached buttons or via external input device such as a mouse, keyboard, trackpad, roller ball, etc.). Initially, the biometric sequence is analyzed to ensure that it was completed properly (e.g., the input device made the proper motions, etc.). If this analysis indicates that the sequence was properly completed, the user-generated biometric sequence is input (either directly or after being vectorized based on pre-defined attributes) into at least one machine learning model that is trained using, at least, the biometric sequences generated during the training period.

In some cases, the at least one machine learning model can also be trained using data generated from other users (e.g., data that characterizes other users' behavior when performing the same or similar biometric sequence).

The output of the at least one machine learning model can, for example, be a score (e.g., a confidence score, etc.) that characterizes the likelihood of the user having generated the biometric sequence input via the computing device (directly or via peripherals). In some cases, a score threshold can be utilized (which may vary user-to-user or which may adaptively change based on user behavior) which, when exceeded, indicates that the inputted biometric sequence was performed by the user. When the scores indicate that the actions were that of the desired user, some or all of the biometric cryptographic key can be made available. In some cases, each attribute of the biometric sequence can have a different key portion which is returned upon the successful determination that such attribute indicates that the corresponding user behavior is that of the user.

Various type of machine learning models can be used including, supervised learning, unsupervised learning, semi-supervised learning, and/or reinforcement learning based models. Further, as noted above, multiple machine learning models may be used either, in parallel, or in a cascading arrangement in which outputs of models are used as inputs (or partial inputs) to other models. Supervised learning models that can be used include: random forests, nearest neighbor models, naive Bayes, decision trees, linear regression models, support vector machines (SVM), and/or neural networks. Unsupervised learning models that can be used include k-means clustering. Bayesian methods (including semi- and non-parametric methods), statistical methods such as bootstrap, and the like. Semi-supervised learning can incorporate elements from both supervised learning and unsupervised learning models. Reinforcement learning models can include Q-learning models, temporal difference (TD) models, deep adversarial networks, and the like.

There are different types of authentication workflows that can be used in connection with the password-less techniques described herein.

In one workflow, an agent can be used to generate a biometric cryptographic key based on a biometric sequence and obtain a domain password to create a stored encrypted passphrase (based on the combination of the generated biometric cryptographic key generated during a training period and the user-provided domain password) that can be used for subsequent authentication once the user enters the same or similar (within pre-defined scoring thresholds, etc.) biometric sequence. With reference to process flow diagram 300 of FIG. 3 , initially, at 310, a user attempts to login into an operating system (e.g., WINDOWS, etc.) of a client device and is presented with a login screen in a graphical user interface. Thereafter, at 320, the user, via the graphical user interface and input device(s), goes through the authentication workflow by performing the biometric sequence specified during the training period. This biometric sequence can be validated (i.e., it can be confirmed that the biometric sequence was properly executed), and additionally, other user behavior attribute data can be (which characterizes how the properly executed biometric sequence was performed). Upon successful authentication, at 330, it can be determined that the user requires a real-time (inline) encryption of the user's current domain password. Next, at 340, an additional screen can be presented in the graphical user interface prompting user to enter the domain password, and then, optionally, a second time to confirm the domain password. After successful conformation of the domain password, at 350, the domain password is then provisioned securely on the client device, based on determination of available security container(s) for subsequent reuse. For example, the encrypted password value corresponding to the domain password can be stored locally in a secure container such as a Trusted Platform Module (TPM), or alternative, the encrypted password value can be stored in the HKLM registry if TPM is not available.

Another authentication workflow relates to subsequent logons in which an encrypted passphrase is decrypted with a real-time collected biometric cryptographic key (derived from the user-generated biometric sequence in the computing device). With reference to process flow diagram 400 of FIG. 4 , initially, at 410, a user attempts to login to the operating system (e.g., WINDOWS, etc.) and domain of a client device. Thereafter, the user is presented, via a graphical user interface, a login screen with an authentication workflow that prompts the user to input a biometric sequence. Next, at 420, user-generated input is received and it is determined that the user properly executed the pre-determined biometric sequence forming part of the authentication workflow. Thereafter, it can be determined, at 430, whether the user behavior when properly executing the biometric sequence indicates that the biometric sequence was executed by the required user. For example, based on a pre-defined set of features that can identify one user behavior from another (e.g., the vectorized attributes, etc.), a confidence score can be generated, by at least one model, for each feature. When the confidence score is above an accepted threshold (which can be fixed or vary), a portion of a biometric cryptographic key is returned. This iterative process can be repeated until each and every input/action has been scored which results in all returned key portions being concatenated to become a final biometric cryptographic key. Subsequently, at 440, the locally stored encrypted value can be decrypted (using, for example, the AES 256 algorithm, etc.) using final biometric cryptographic key resulting in the domain password. Later, at 450, an operating systems credential provider can use the decrypted domain password to log the user into the operating system and to the domain.

Another authentication workflow relates to scenarios in which a password has expired and/or an invalid password has been repeatedly been entered (causing the system to lock out the user). With reference to diagram 500 of FIG. 5 , at 510, a user is presented with a graphical user interface allowing him or her to attempt to login to an operating system and a domain. Thereafter, the user executes a biometric sequence as described above. Next, at 520, upon successful completion of the biometric sequence (both sequence and user behavior-wise), the provisioned domain password is extracted. The operating system then, at 530, indicates that the password is expired or otherwise invalid. It is then determined, at 540, that the user requires inline re-provisioning of the domain password. Next, at 550, an additional screen is shown in the graphical user interface that prompts the user to enter the domain password, and, optionally, then a second time to confirm the domain password.

The domain password is then, at 560, re-provisioned securely, based on determination of available security container(s). This re-provisioning can include generating, using at least one model, a confidence score for each feature based on a pre-defined set of features (i.e., vectorized attributes, etc.) that can identify one user behavior from another. When the confidence score is above the accepted threshold, a portion of a biometric cryptographic key is returned. This process can be repeated until each and every input has been scored and all returned key portions will be concatenated to become the final biometric cryptographic key. The domain password is then encrypted using, for example, the AES 256 algorithm, with the biometric cryptographic key. The encrypted password value can then be stored locally in a secure container, like a Trusted Platform Module (TPM), if available. Alternatively, the encrypted password value can be stored in the HKLM registry if TPM is not available

The operating system credential provider can use the supplied domain password to log the user into the operating system and to the domain.

FIG. 6 is a process flow diagram in which, at 610, data is received, as part of an authentication procedure to identify a user, that characterizes a user-generated biometric sequence. The user-generated biometric sequence is generated by the user interacting with at least one input device according to a desired biometric sequence. Thereafter, at 620, the user is authenticated, using the received data and at least one machine learning model trained using empirically derived historical data generated by a plurality of user-generated biometric sequences (e.g., user-generated biometric sequences according to the desired biometric sequence), if an output of the at least one machine learning model is above a threshold. In some cases, the threshold is pre-defined (for example based on confidence level). In other cases, the threshold may be based on another mapping from the output of the at least one machine learning model to confidence level, and such mapping can change dynamically. Subsequently, at 630, data is provided (e.g., loaded into memory, stored, displayed, transmitted, etc.) that characterizes the authenticating.
